<div>I see you are setting EO = Forced on the CUBE, which the telco requires, but are you using EO on the SIP trunk form CUCM to the CUBE? What is your DTMF Signaling Method set to on that Trunk?</div><div><br></div><div>
The only command I run which I can see is missing from your config is:</div><div><br></div><div>voice service voip</div><div> dtmf-interworking rtp-nte</div><div><br></div><div>But I'm not positive that's your problem.</div>
